iOptron CEM120 center-balanced equatorial mount

iOptron's CEM120 Center Balanced Equatorial Mount, is a significant addition to its lineup, priced at $5,128. This mount is designed to meet the increasing demand for a stable and accurate platform capable of carrying larger instruments and complex imaging arrays. The CEM120's unique "center balance" design ensures the payload's weight is focused directly over the center of the pier or tripod, providing natural stability and precision in operation.

The mount boasts an impressive payload capacity of 115 lbs (52 kg), while the mount itself weighs only 57 lbs (26 kg). This high payload-to-weight ratio makes it an attractive option for both visual observers and astrophotographers. The CEM120 is equipped with precision gear clutches and an advanced cable management system, which minimizes the risk of tangled cables and potential damage. The system includes various ports strategically located for optimal cable routing.

A standout feature of the CEM120 is its low periodic tracking error of less than ±3.5 arc seconds, ensuring high precision during observations and imaging sessions. The mount's tracking accuracy is further enhanced by the inclusion of a precision stepper motor with 0.07 arcsecond resolution, allowing for smooth and accurate GOTO movements. The Go2Nova 8410 controller, equipped with Advanced GOTONOVA GOTO Technology, provides users with an easy-to-use interface and reliable operation.

For those needing remote control capabilities, the CEM120 includes built-in Wi-Fi and LAN connectivity. This feature enables users to operate the mount remotely, making it a convenient choice for observatories and remote setups. Additionally, the mount is equipped with a 32-channel Global Positioning System (GPS) for precise location data, an integrated ST-4 autoguiding port, and a Losmandy D saddle for secure attachment of optical tubes.

The CEM120 also offers flexibility in mounting options, with an optional heavy-duty Tri-Pier 360 or a Permanent Pier for increased stability. For lighter payloads, a Tri-Pier adapter (8036-120) is available and can be adapted for permanent pier mounting. The mount's altitude and azimuth adjustments are precise, with a range of 0° to 68° for latitude and ±5° for azimuth, facilitating easy alignment and setup.

The mount includes several practical features, such as a polar alignment routine for users unable to see the Pole Star and a meridian treatment that can stop or auto-flip, depending on user preferences. The CEM120's power requirements are modest, with a consumption of 0.7A during tracking and 1.8A during GOTO operations, powered by a DC 12V, 5A supply.

iOptron offers optional extended warranties for the CEM120, with choices ranging from one to three years. The standard package includes the mount head, a Go2Nova 8407 V2 hand controller, a counterweight shaft, and two 10 kg counterweights. This comprehensive setup ensures that users have everything needed for immediate operation.

Overall, the iOptron CEM120 Center Balanced Equatorial Mount stands out as a versatile and robust option for both amateur and professional astronomers, offering a combination of high payload capacity, precision tracking, and user-friendly features. Its design and capabilities make it a valuable tool for anyone looking to explore the skies with accuracy and stability.
